Nettet9. mar. 2015 · This guarantees that the estimated drift term converges to its true value exponentially. The observer is used in conjuncture with a control law to obtain asymptotic tracking and path following in the presence of ocean currents. The second contribution is a direct adaptive integral line-of-sight controller for path following.
Nettet3. Line-of-sight based model predictive control 3.1. Line-of-sight guidance system A conventional surface vehicle tracking control system is usually implemented using a standard PID autopilot in series with an LOS guidance as shown in Fig. 2.

Note the right angles between the line of sight and the Earth radius R 0 at the tangent point, which means we have two right triangles. radiuskopffraktur icd 10Nettet1. sep. 2003 · The Line-of-Sight guidance principle. ing algorithm. To avoid large bumps in tP d when switching, and to provide the necessary derivatives of tP d to the controller, the commanded LOS heading is fed through a reference model.
